MACHINE FOR PRODUCING RECTILINEAR RECIPROCATING MOTION.

SPECIFICATION forming part of Letters Patent No. 332,708, dated December22, 1885.

Application filed April 13, 1885.

To all whom it may concern:

Be it known that 1, JAMES M. FURLONG, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Machines for Producing a Rectilinear Reciprocating Motion, whichimprovement is fully set forth in the following specification and shownin the accompanying drawings.

The object of my invention is to produce an improved machine by which aregular rectilinear reciprocating motion may be produced for the purposeof burnishing, sawing, drilling rock, pumping water, and for other uses,said machine being composed of parts and devices as fully set forth inthe following specification, and more particularly pointed out in theclaims.

As shown in the drawings this machine is represented as being suppliedwith tools for the purpose of setting the edges of the soles of shoesand burnishing the bottom surfaces of said shoe-soles.

Referring to the drawings, Figure 1, Sheet 1, is a side elevation of themachine, parts being broken away and omitted, and one of the sleevescentrally longitudinally sectioned to show one arm of the reciprocatingshaft as it rests in said sleeve; Fig. 2, a plan of the central part ofthe same with the right sleeve and cross-arm viewed as indicated byarrow 00 in Fig. 1, parts being horizontally and cen trally sectioned,as on the dotted line 00 in Fig. 1, to expose to view some of theinterior parts of the machine; Fig. 3, a similar view of the left sleeveand cross-arm; Fig. 4, an end elevation of some of the upper parts ofthe machine, viewed as indicated by arrow in Fig. 3, serving to showmore fully the manner in which the edge setting and burnishing irons areheld; Fig. 5, an elevation of a portion at the end of the right sleeve,seen as in Fig. 1, showing an edge-setter, instead of the crossarm,secured to the end of the main reciprocating arm, parts being centrallyand vertically sectioned; Fig. 6, a view of the parts shown in Fig. 5,viewed as indicated by arrow in said latter figure, showing, further,the manner of securing in place the tool stock or head; Fig. 7 anelevation of a headed socket for holding an edge-setting or other tool,

drawn to a larger scale, said socket being in part vertically centrallysectioned to show the manner of fitting the tool, the retaining-spring,

and pin for the tool, shown in full and dotted line positions; Fig. 8, aside elevation of the tool and holder shown in Fig. 5, drawn to a largerscale to show more clearly some of the minor parts of said holder, theloosely-fitting tool being shown in full and dotted line positions; Fig.9, a vertical central section of the slotted head for the reciprocatingarms, sectioned as on the dotted line y in Fig. 1, and viewed asindicated by arrow 1, drawn to show more clearly the crank-pin andfrictionsleeve as they occupy the slot in the head; Fig. 10, a verticalsection of the same head out as on the dotted line 2 in Fig. 9, andviewed as indicated by the arrow therein, the crank-pin and head beingshown in full and dotted lines on opposite sides of the axis of theshaft, a portion of the reciprocating arms being also shown in dottedlines on each side of the head; Fig. 11, Sheet 2, an elevation of theupper part of the machine, similar to that shown in Fig. 1, Sheet 1,drawn to show the adjustable finger-rest for the operator, near theedge-setting tool, and a manner of holding the same; and Fig. 12, a viewof the finger-rest and combined parts viewed as indicated by arrow inFig. 11, showing the rest in dotted lines as turned or adjusted to theopposite side of the edge-setting tool.

Referring to the parts, A isa suitable standard or pedestal forsupporting the working parts of the machine,which, as shown in Fig. 1,stands upon the floor of the room, but may be made shorter and placedupon a workbench; B, asleeveblock carrying the reciproeating arms f andg, crank-shaft a, and other working parts of the machine, resting uponand secured to the upper end of the pedestal A. The sleeve-block isprovided with three sleeves, O, D, and F, having their axes in the samehorizontal plane, the sleeves O and D be- 9 ing equal and extending inopposite directions from the sleeve-block in a right line, the sleeve Fbeing made shorter than the other sleeves and forming right anglestherewith.

a is ashaft resting in the caliber of the sleeve F, provided at itsinner end with a crank-disk or crank, b, resting within or 00- cupying acavity, 0, in the sleeve-block, and at its outer end provided with aband-wheel, d, and inertia-wheel G, as shown in Fig. 2.

Theinner ends of the arms f and g are secured to a reciprocating head,e,occupying the cavity a in the sleeve-block contiguous to the crank andbeing moved or reciprocated laterally within said cavity by the crank.This reciprocation of the head by the crank gives to the edge settingand attached tools their proper motion, the reciprocated arms f and 9moving along their bearings in the sleeves O and D. The head 6 is formedwith a face, 8, turned next the face of the crank, as shown in Fig. 9,and the slot h in the headopens out only at that face, or is turnedtoward the face of the crank, as shown. Thecavity orrecess his not cutthrough the head at any point, but is inclosed on all sides, exceptingas it opens out at the face 8 of the head, and this face being turnedtoward the face ofthe crank and being contiguous therewith, entirelyincloses the said cavity. A friction-sleeve, or roller, 0, fits the pinso as to turn freely thereon, and also fits between the sides of theslot h, the employment of which sleeve greatly reduces the frictionbetween the parts in contact.

It will be readily understood from Fig. 10 that a rotation of the crankwill result in moving the head 6 laterally across by the end of theshaft a, while there will be no vertical motion of the head from thefact that the pin is permitted to move freely up and down in the slot,the latter being sufficiently long to ac commodate the pin in itsvertical movement. The reciprocating armsf and g project beyond the endsofthe sleeves, and are provided near their outer ends each with a fixedcollar, n, the extreme ends of the arms being threaded to receivescrew-nuts r. A blank space, 70, is left between each nut and collar toform a seat upon which to receive a square tool-stock, t, as shown, thelatter being pinched and firmly held between said nutand collar. Whenthus constructed, a'tool may be held at the outer end of each Of'thB twoarms 9 andf, enabling two operatives to work at the machinesimultaneously.

H and I are two similar cross-arms, each composed of two short arms, inm and pp, secured to opposite sides of heads or blocks t, the two armssecured to the same head forming a horizontal right line at right angleswith the line of the arms f and 9. At their outer ends these cross-armsare provided with fixed collars n, and screwthreads like those on thereciprocating armsf and g, and screw-nuts 1", there being seats t, uponwhich to receive tool-stocks Z, the same as the seats 7con the arms fand 9, above described. The headst are of the same size as thetool-stocks Z, made so to be interchangeable with said tool-stocks, sothat the latter may be removed from the reciprocating arms f and g, andthe heads slipped thereon instead and held by the said screw-nuts 1".When these cross-arms are put upon the arms f and 9, an operator may beemployed at work at each of the four outer free ends of the twocrossarms, the reciprocating motion given the armsf and g by the crankmoving all four tools alike. The crossarms H and I, when secured to theends of the reciprocating armsf and 9, move or reciprocate laterally orsidewise, as indicated by dotted lines in Fig. 2.

b are edge-setting tools, or tools used for shaping and burnishing theedge of the soles of the shoes, the blades a of the tool bearing uponthe bottom face of the sole of the shoe, while the surfaces 8 burnishthe edge of the sole. when being used, is in a line substantially Themotion of the edge setting tool,

parallel with the plane of the blade a of the tool. This tool may beformed with a tapershaft '0, as shown in Fig. 7, and fitted in atapering socket, d, of the tool -stock Z, with a retaining-pin, a, andslenderspring c,secured to the socket in position to hold the point ofthe pin in a cavity, 0, of the shank. The pin and spring are made light,as their only duty is to prevent the tool dropping out of the socket orholder. The shank t of the tool is purposely fitted loose in the socket,as it is found betterto give the tool a slight lost motion than .to haveit rigid in its socket or holder.

Another manner of holding the edge-setting tool is shown in Figs. 5, 6,and 8, in which a horizontal tool-holder, K, is bored and internallythreaded to fit the end of the reciprocating armf or gin the place of ascrew-nut, and vertically slotted at its outer end to receive the tool.

The manner ofsecuring the tool to the holder is clearly shown in Figs. 5and 6, the sides of the tool being recessed to receive the jaws f of theholder. A pin, 0, crossing the space between the 'jaws on the outside ofthe tool and entering orifices in both of the jaws, serves "to hold thetool from moving horizontally out of saidjaws. Sufficient looseness isgiven the tool in its bearings within the holder to allow of a slightplay therein, as indicated by dotted lines in Fig. 8.

At L, Fig. 4, is shown a tool for burnishing the soles of shoes, shownalso in dotted lines in Fig. 3. This tool is shown as held to the ICOend of the reciprocating arm 9, and from its position moves sidewise.

1?, Figs. 11 and 12, shows a rest for the index-finger of the hand ofthe operator, to be used while operating upon the toe portion oftheshoe-sole. This rest is formed with an eyelet, g, at its upper'end toreceive the finger of the operator, and a foot, h, reaches laterally toreceive a vertical pivot-bolt, 7a, which latter secures the finger-restrigidly to a supporting-arm, 0, reaching out from the pedestal, asshown. The axis of the bolt is is designed to coincide with the line ofthe axis of the tool b over it, so the rest may be turned and providedwith the horizontal sleeves D horizontally upon the bolt to acorresponding position on the opposite side of the tool, as indicated indotted lines in Fig. 12, thus being adjustable. This is to permit anoperator to work at the edge-setter facing in either of twodirections,which choice of directions in which he faces is frequently ofgreat importance.

When the finger-rest is shifted from one side of the tool to the other,as stated, the tool is of course rotated or turned one-half around uponits axis by the tool-stock or head being removed from the arm andreplaced thereon facing in the opposite direction.

It will be seen from Figs. 9 and 10 that the slot h opens out of no partof the head 6, eX- cepting at the face 8, next the crank b, so that whenthe parts are together said slot is wholly inclosed and unseen, whichprevents dust or other extraneous matter from collecting thereinandclogging or interfering with the working of the crankpin andfrictionsleeve in the slot.
